CVE-2025-4476-Exploit
CVE-2025-4476-Exploit A small Python test client to send HTTP GET requests with an oversized Authorization: Basic header. This tool is intended for lab testing and research into header-parsing issues e.g., null-dereference / crash bugs such as CVE-2025-4476 in libsoup. It demonstrates how a...
RLSA-2026:98560 Important: libsoup3 security update
Libsoup is an HTTP library implementation in C. It was originally part of a SOAP Simple Object Access Protocol implementation called Soup, but the SOAP and non-SOAP parts have now been split into separate packages. libsoup uses the Glib main loop and is designed to work well with GTK applications...

Important: libsoup3
Issue Overview: A flaw was found in libsoup. The soupuridecodedatauri function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling gbase64decodeinplace. If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and b...
libsoup: libsoup: Heap buffer overflow via uninitialized length in data-URI base64 decoding
A flaw was found in libsoup. The soupuridecodedatauri function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling gbase64decodeinplace. If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the si...
libsoup: libsoup: Heap buffer overflow from WebSocket Pong signal type confusion
A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection emitted the ::pong signal with a GByteArray pointer even though the signal is declared to pass a GBytes. Applications connecting a handler that follows the documented GBytes API can trigger heap...
libsoup: libsoup: Heap use-after-free in libsoup HTTP/2 client on_data_read() via GOAWAY during body upload
A flaw was found in libsoup. A malicious HTTP/2 server or a Man-in-the-Middle MITM attacker can exploit a heap use-after-free vulnerability in the HTTP/2 client implementation. This occurs when a GNOME application uploads a file using HTTP/2, and the server sends a GOAWAY frame while the file bod...
libsoup: libsoup: Heap buffer overflow during WebSocket message reassembly
A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteArray, libsoup did not adequately cap total message size against the limits of the underlying buffer type. A remote peer could send fragments that caused size truncation while the implementation still used th...
libsoup: libsoup: Heap buffer overflow during WebSocket receive-buffer growth
A flaw was found in libsoup. When max-incoming-payload-size is unlimited 0, SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data...
libsoup: libsoup: Heap buffer overflow during outgoing permessage-deflate buffer growth
A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow...
SoupWebsocketExtensionDeflate: libsoup: libsoup: WebSocket permessage-deflate Unbounded Decompression Remote Denial of Service
A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop inflate processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via...
libsoup: SoupWebsocketConnection: libsoup: WebSocket remote denial of service via oversized control frame protocol violation
A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames e.g., PING, PONG, CLOSE contain a payload of 125 bytes or less. A remote, unauthenticated attacker...
libsoup: libsoup: Heap buffer overflow during WebSocket client-frame masking
A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow...
OESA-2026-4781 libsoup security update
libsoup is an HTTP client/server library for GNOME. It uses GObjects and the glib main loop, to integrate well with GNOME applications, and also has a synchronous API, for use in threaded applications. Security Fixes: A flaw was found in libsoup. When handling an incoming WebSocket Pong frame,...
